.t -novrn that llnxnvll. ilci'iuononu, of the 1721' ed Stat residing at 51", in the county of Lnyahoga and i Clhio, have invented certain. new useful Improvements in Stop and a cla's, ot which the following a invention relates to an improvement p and Waste cocks, and the inventlon its in a coupling member having a tied at one side thereof and adapted to "trol "the .ivaste as \vell as serving other iortant purposes, all substantially as Wu and des *rihcd and particularly pointit '4 i 1' the acconqianying draivinus, Figure 1 side elevation oi a coupling in section and showing the main valve ed therein and the controlling head of we waste valve. Fig. 2 is'a plan view on line Pr-2, F 1, showing especially the n'aste valve and its construction and seat.

3 is a cross section on a line corresponding to line 33, Fig. 2, with the Waste down.

cveral material advantages are obtained constructing a. Waste mechanism. as thus connection with the main valve h comprises not only the individual ing and closing of the waste at will host manipulating the main'valve but it so provides exceptional means for making pairs on the main valve and for cleaning the opening for the Waste valve as Well as ing a guide in the'vvaste valve for the 'allation thereof on the right side, all as hereinafter fully appear. main member consists in a union or c constructed at its ends internally '-'l,':3'-l11'2l(l$ to make the usual pipe ions and providedat its middle inwith a valve seats and an internally ded neck 9' opposite said seat in which rnally threaded head 7' of the valve 0 atably engaged. A suitable cap 70 sursaid neck and a packing 12 therein 1 the of fluid about said stem. Of course liea tures of construction in themselves in valve o with the Waste valve 4. The

valve stem prevents possible e not new in compression :valves but the eltv resides in the combination of the d valve is. of the needle or beveled or pling (.1 at right angles to valve 0 and at the Waste site of said. valve in the coupling in the base of a nipple a projecting filli Watltl from said coupling. The seat for valve l is tapered to provide a sharp edge seat for the pointed end of the Waste orifice G. The space about the said seat is enlarged as compared with the body of valve i so as to afford a fluid space about and the stem m is screw threaded into the nipple n and has a duct (Z centrally lengthwise with an entrance or openingin the head of valve at back of its seating portion and discharging through the milled or knurled head h. opened the Waste will discha ge through the d not or bore d in the stem thereof, and the said valve thus made an independent member adapted to be opened and closed alone and apart from main valve 2). However. and obviously, the said valves are mutually and operatively related, and the valve a controls the flow oi Water through the vcoupling While valve dcontrols the waste when said main valve is closed. A half turn of the valve will open waste sutli cientl v, and by having an individual valve of this hind it can be easily removed for cleansing the passage, Whereas With the old plug type of valve and a Waste orifice 0011* trolleo thereby, the plug itself had to be removed for cleansing and the Water had to be turned oil the line. Manifest advantage also accrues in the installation of the coupling by having a special waste of this kind, as above noted, the valve being at the side of the main valve helping to locate the Waste in the right place.

A horizontal or other position. of the joint or coupling 0 may be used. In F 3 the Waste is shown at the bottom or down. Usually the Waste coupling so positioned that it is protected from the frost by its position and hence almost any position which a particular location may impose may be safely adopted in placing the joint, The Waste side or portion of the joint 0 obviously is the one open to the pipe which is exposed to freezing andistobe emptied, While the other'sideor portion-is constantly open to the service pipe.

lVhat I1claim is:

'1. In stop and-Waste cocks, a body havinga main Water passage and valve seaft, ;a valve chamber and a reciprocable. selves? It follows when valve 4 is I posite said seat, a Waste nipple projecting outward from said body between one end and the transverse median line of said body and in the same plane approximately as the valve seat, and a Waste valve for said Waste nipple.

In stop-and Waste cocks, a chambered body having opposite ends internally screw said Waste-nipple having a central Waste passage and an outer finger-gripping member.

- therefrom.

3. In a stop andwaste cock,-a chambered coupling body having a neck. and a main valve seatcentrally between its ends and aradially-projecting nipple at one side of the longitudinal median line of said body between one of its endsand' thevalve seat and beneath the plane of said-seat, a reciprocable valve Within said .neck opposite the main valve seat, and a rotatable screw valve for said nipple to control the flow of Waste:
